Stance on Climate Change
“Global warming hysteria is politics, not science. If the IPCC enterprise were science, it would at least make a good faith effort to deal with major defects in the temperature data, like the UHIE. Alarmists refuse to address the UHIE [Urban Heat Island Effect] not because they have a plausible case that it doesn’t exist–they don’t–but because there is an enormous amount of money being made by promoting “green” energy. You should read the comments to Dr. Spencer’s post; they draw out the difficulty of properly understanding and quantifying the urban heat island effect.” 
“The fact is that global warming alarmism is a well-funded industry. The United States government alone has contributed billions of dollars to promote global warming alarmists, and nothing to the voices of scientific sanity. What is going on here is that the alarmists, knowing their science is shaky at best, cannot tolerate diversity of thought. They know that if critics are allowed to exist, their “scientific” house of cards will come tumbling down. So they must silence every dissenting voice; otherwise, the gravy train might end.
It isn’t pretty, but this is what happens when you make science subservient to a political agenda.”

“There are many more problems with the data on which global warming hysteria rests; for example, those who have inspected weather stations in the U.S. have reported that well over half are out of compliance with standards for such stations, e.g. because they are next to heating vents.” 
“Michael Mann, perpetrator of the notorious hockey stick hoax, is one of the world’s execrable characters. On top of his more important bad qualities, he is a whiner. The self-pitying Mann complains that scientists and organizations that are skeptical of the alarmists’ claims—like the now-ridiculed hockey stick—get tiny amounts of funding from concerned citizens.”

John Hinderaker writes a blog post on Powerlineblog.com titled, “Global Warming Alarmists Resort to Hoax,” referring to the “Confidential Memo: 2012 Heartland Climate Strategy.” Within the post, Hinderaker writes, “The Heartland Institute is a superb organization that deals with a number of issues including climate science. We have cited Heartland’s research many times.”  Further on, he states, “Let me be perfectly clear: I think it is obvious that Peter Gleick fabricated this document—the only one he posted that makes the Heartland Institute look bad—because the real ones he stole from Heartland didn’t serve his partisan purpose. Or, if he didn’t make it up himself, he got it from an ally who fabricated it. No knowledgeable person could mistake Gleick’s hoax for a legitimate top-secret Heartland memo.”
